A method for sharing geometric information and maintaining parametric consistency amongst different software applications in a collaborative environment is presented. The method is based on geometric information sharing via neutral files, and incorporates Internet based messaging mechanisms amongst applications to maintain the parametric control over the exchanged geometry. In a preferred embodiment the proposed method is applied to Heterogeneous Assembly Modeling (HAM). By means of the presently disclosed method, within the heterogeneous assembly model, the parametric control over part geometry is maintained, even though the parts are imported in the assembly via neutral files originated by other CAD applications.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of sharing geometric information in a collaborative design environment between a designer and at least one part provider comprising: subscribing, by a designer and by at least one part provider, to a service marketplace; receiving, by said designer, a part file from one of said at least one part provider, said part file containing information relating to a part; incorporating, by said designer, said part file into a design; requesting, by said designer, a parametric change to said part from said part provider through said service marketplace; receiving, by said designer, an updated part file from said part provider through said service marketplace; and incorporating, by said designer, said updated part file into said design.
2. The method of claim 1 wherein said receiving a part file comprises receiving a part file in a neutral file format from a provider service marketplace model, the provider service marketplace model receiving data from a CAD model and translating said CAD model data into said neutral file format.
3. The method of claim 1 wherein the incorporating further comprises: receiving said part file at a designer service marketplace model; and providing part information to a designer CAD model.
4. The method of claim 1 wherein said requesting further comprises: providing a parameter change to the designer service marketplace model; propagating the change through the service marketplace to the provider service marketplace model; relaying the change to the provider CAD model; and rebuilding the providers CAD model.
5. The method of claim 4 wherein said receiving an updated part file comprises receiving in the designer service marketplace model an updated part file in a neutral file format from a provider service marketplace model, the provider service marketplace model receiving data from the CAD model and translating said CAD model data into said neutral file format.
6. The method of claim 5 wherein said incorporating comprises propagating said updates part file from said designer service marketplace model into the designer CAD model and producing a new assembly including said updated parts file.
7. The method of claim 1 further comprising calculating new properties from said design including said updated part file.
8. The method of claim 1 wherein said steps of receiving a part file and receiving an updated part file are performed across a network.
9. The method of claim 8 wherein said network comprises the Internet.
